With the weekend looming, the organisers at the Aspen Center for Physics gave a short presentation on hiking in the local area. The sun was shining as we entered the auditorium, lighting up inviting green hills up which a stream of gondolas were gaily making their way. Everyone from the elderly professors to the young researchers clutching babies was keen to get outside.

The speaker was a retired Physicist from Chicago who started his speech with a clear pronouncement that he proceeded to repeat:

"If you want to go hiking, you should find someone who has been before. What we call an expert."

I looked sceptically out at the landscape around one of America's most up-scale tourist centres. Of course, all hiking had risks, but the walks around Aspen were not known for being technically difficult. Our guide however, was most insistent. A waterproof coat was essential if you were even looking in the direction of a mountain. As was a topologically detailed map, a cell phone (although this wouldn't work, so relying on it would result in DEATH) and you should inform at least three people and a lamppost where you were going and when you were expected back.

It was sound advice but presented with a strong side-dollop of terror, which swiftly became the main course as our host warmed up to the theme.

For Cinderella, the time of destruction was midnight, but for us hikers in Aspen, it was midday. Be up on the mountain after this time and a lightening storm would descend upon you, causing your hair to stand on end and leaving you nowhere to run. Then you would be electrocuted and promptly eaten by a bear. The end.

These instructions were followed by a tale of warning about a Physicist from the centre who went missing for three days. Apparently, despite having a topological map and other appropriate equipment, he became lost. Because he was a loner, no one noticed he was gone until his wife called the Sheriff's office after not hearing from him for two nights.

That could be YOU, you friendless socially awkward geeks

was the unvocalised message.

After fifteen minutes, a blue booklet listing walks was waved at us and our speaker departed with a cheerful, "I strongly encourage you all to get out and about!"

There was stunned silence in the auditorium.

This event was directly followed by a seminar on 'crumpling'. Yep, that's right - an entire scientific seminar on crumpling paper. Or Physicists. Somehow it was oddly appropriate.
